这是编译原理里面用来判断输入的东西是是否是符合数学运算公式...

java写的PLO词法分析,刚交了作业 没什么大内容,仅供参考-java write lexical analysis of the PLO, has just paid a little big operation, for reference purposes only

VC环境下实现的词法分析，语法分析程序 VC VC VC-VC environment under the lexical analysis, grammar analysis procedures VC VC VC

一个简单的解析器，可以对四则运算和if语句进行解析，利用简单扫描的方式词法解析，和压栈方式解释运算，可以帮助学习编译原理-a simple parser can be four operators and if statements for the analysis, simple scanning the lexical analysis, and interpretation Yazhan Operators can help compiler theory

这里以开始定义的PASCAL语言子集的源程序作为词法分析程序的输入数据。在词法分析中，自文 件头开始扫描源程序字符，一旦发现符合“单词”定义的源程序字符串时，将它翻译成固定长度的单 词内部表示，并查填适当的信息表。经过词法分析后，源程序字符串（源程序的外部表示）被翻译成 具有等长信息的单词串（源程序的内部表示），并产生两个表格：常数表和标识符表，它们分别包含 了源程序中的所有常数和所有标识符。- Here starts the PASCAL language subset source program which defines to take the lexical analyaer the data-in. In the lexical analysis, starts from the article article to scan the source program character, once discovered when conforms to "the word" the definition source program character string, translates it the fixed length the word interior to indicate, and looks up fills in the suitable information table. After the lexical analysis, the source program character string (source program exterior expression) is translated has and so on the long information the word string (source program internal expression), and produces two forms: The chart and the identifier table, they have separately contained in source program all constants and all identifiers.

编译原理课程的试验中的语法分析部分，程序比较长，附带报告-compiler theory courses in grammar test analysis, long procedures, fringe report
